I'm not familiar with that video at all, but he might mean that if you repeatedly add process noise (P = FPF' + Q) but never reduce P via measurement, then P can only increase. In general, though, I would caution you against considering the covariance matrix P as...
This is a known issue with 3.X and has been previously fixed for 4.X and is resolved in the current public release of 4.X. There is a workaround for 3.x, however. With the code you provided, the compiler output is truncating the result by only doing integer math. This was...
n is a number in the range 0 <= n < 256*256. It takes two bytes to express that number since one byte can encode a value from 0 to 255. hi,lo=n/256, n%256 is the same as hi = n / 256 lo = n % 256 / is the...
You do not initialize feed correctly. final JTextArea feed = new JTextArea(30,50); This does not initialize the field feed but instead creates a new local variable of the same name. Try turning final JTextArea feed = new JTextArea(30,50); into feed = new JTextArea(30,50);....

Yes, by only specifying the noindex, it will still be follow. More information can be found [here]{https://developers.google.com/webmasters/control-crawl-index/docs/robots_meta_tag}
Technically, you can't have two sketches on one board. It's not really a different program. The switch automatically: You don't even need any extra hardware for this approach. Just turn on the pullup resistors in your board with this code: pinMode(pin, INPUT); // set pin to input digitalWrite(pin, HIGH); //...

The short answer is yes you can. However, you must be sure to use the right voltages. Connect +5V to L293D:VCC1 Connect +7.2V to L293:VCC2 The raspberry pi has 3.3V logic levels, but this should be sufficient to enable the input pins of the L293D. Also make sure to connect...
you can do that without writing file in your local machine by using the following code ByteArrayOutputStream bos=new ByteArrayOutputStream(); byte[] imageByte = null; try { //To Get the the size of the screen. Rectangle screenRect = new Rectangle(Toolkit .getDefaultToolkit().getScreenSize()); //To Store the scrreen shot in buffer. BufferedImage capture = new...
Solving the predicament in picture 2 could be as simple as checking for other white squares around the robot before you make a move. In picture 2 the robot would see that the square he is facing is "greyed out" and decide to check all other directions and eventually find...
Since this is Controller Mode, I'm assuming that you are setting the motors to stop when the corresponding button is not pressed. if([...]) [...] else { setMotorSpeed(motor10, 0); } This is the cause for the stopping of the motors when you release. All of the other methods that you tried...
public void method1 (int x) { if (x == 1) { try { Robot r = new Robot(); // R is defined in the try block. It is not visible outside of this block. } catch (AWTException e) { // TODO Auto-generated catch block e.printStackTrace(); } r.mouseMove(50,50); // R is...
'a' evaluates to 97 in UTF-8. KeyStroke.getKeyCode() simply returns an integer representation of 'a'....
